Design and Comparative Analysis of Ladder Frame Truck Chassis

Abstract

This research paper titled "Design and Analysis of Chassis" aims to investigate the mechanical behavior of three different materials namely Steel alloy302, Steel alloy4130, and AA 7068 on different cross-sectional shapes of a ladder frame chassis - C, I, and Box (Hollow). The design of the chassis is created using Solid Works 2013 software, and static analysis is conducted using Ansys software R18.0. The results obtained from the analysis provide information on the total deformation, equivalent strain, and equivalent stress of each material on different cross-sectional shapes. For the C type cross-section, it is observed that Steel alloy302 and Steel alloy4130 have higher total deformation and equivalent strain compared to AA 7068. However, the equivalent stress is higher for AA 7068. For the I type cross-section, Steel alloy4130 shows the highest total deformation and equivalent strain, while AA 7068 exhibits the highest equivalent stress. Finally, for the Box (Hollow) type cross-section, the total deformation and equivalent strain are highest for Steel alloy4130, and the equivalent stress is highest for Steel alloy302. These results provide valuable insights into the behaviour of different materials on different cross- sectional shapes of a ladder frame chassis. The findings can be utilized to optimize the design of the chassis for better performance and durability. The study emphasizes the importance of material selection and cross-sectional shape in the design of a chassis for various applications. Key Words: Chassis, SOLIDWORKS Modelling, Static Analysis
